Maria...welcome to OCF. There are peopel on there that have Hyberbaric treatments. I'm sure they will post and let you know what to expect. Do you already have an oral surgeon that you see, or is your Monday appointment the first time you will meet them? I see you are in NJ and I am too. Were in NJ are you. I know of 2 awesome oral surgeons in PA. Just a thought if you are not already established with someone. Send me a PM if you are interested in discussing.
